I get this error at the linker stage when compiling the webkit-1.1.5 package on my Ubuntu 9.04 box:

I'd like some pointers on how to attack this problem, either by looking into the "hidden sybmol" error or by helping me understand what the "Nonrepresentable section on output" message from the linker actually means.

I have already checked that this is consistent behaviour that persists across a make clean;make invocation.

A: 

I've received the "nonrepresentable section on output" error when crosscompiling for ARM and some of the libraries was not correctly compiled with -fPIC. Pretty sure that's not the error here though...

+1  A: 

Please try removing the -fvisibility=hidden option from the commandline. It will produce a larger object (with some unnecessary symbols, which won't matter in the end because it is an execultable), but should eliminate the problem. This is not a solution; rather a workaround. Please check (this is just a hunch) if there are no libc version mismatches between libraries and GtkLauncher.o

looks like -fvisibility=hidden is a somewhat new feature in gcc. Or the docs haven't been updated and are still saying it's new... Maybe it's causing you trouble with some compiler-added safety checks to defend against stack attacks (stack_chk...), if some code was compiled with defenses turned on, and some wasn't?
